Description

Technical Field

[0001] This invention relates to the field of release paper lamination, and in particular to a multi-layer composite release paper lamination device. Background Technology

[0002] Release paper is a type of anti-sticking paper used to prevent prepreg from sticking together and protecting it from contamination; it is also known as release liner or silicone paper. Multi-layer composite release paper laminating equipment is an industrial device used to bond multiple layers of release paper to other materials, and is widely used in industries such as electronics and packaging.

[0003] The working principle of the multi-layer composite release paper laminating equipment is as follows: the release paper and adhesive film are wound separately onto their respective unwinding mechanisms. Driven by the drive mechanism, the release paper and adhesive film are unwound. The positioning mechanism accurately places the multi-layer label into the anti-sticking area of ​​the release paper. Then, the pressure rollers and other devices of the laminating mechanism squeeze and bond the release paper, multi-layer label, and adhesive film together. Finally, the winding mechanism rewinds the bonded product. For cases requiring coating, the corresponding material is first coated on the release paper, and after drying and curing, the product is then laminated.

[0004] Existing multi-layer composite release paper laminating equipment mostly uses pre-made adhesive molds to directly bond the release paper. However, in existing laminating setups, it is inconvenient to clean the surface of the release paper during operation. The release paper surface often has static electricity, making it highly susceptible to attracting dust particles, which reduces the bonding quality with the adhesive film and may even lead to weak adhesion. Furthermore, it is inconvenient to promptly and conveniently change rolls of release paper after unwinding. Moreover, different actual needs may require different numbers of composite release paper layers, and existing equipment is not convenient for modular adjustments to quickly produce release paper with different composite layer numbers. Therefore, a multi-layer composite release paper laminating equipment is proposed. Summary of the Invention

[0005] To overcome the shortcomings of existing technologies, this invention proposes a multi-layer composite release paper laminating device that can clean the release paper to ensure stable and firm subsequent lamination, while also facilitating efficient roll changing and modular adjustment to enable the production of release papers with different composite layer numbers.

[0006] To solve the above-mentioned technical problems, the basic technical solution proposed by this invention is as follows:

[0007] A multi-layer composite release paper laminating device includes a support frame with a bracket connected to it. The support frame also has two laminating rollers, one upper and one lower.

Release paper is wound around the outer side of the release paper roller and passes between the upper and lower laminating rollers. A variable frequency motor is installed on the inner walls of both sides of the support frame. The output ends of the variable frequency motors on both sides, close to each other, are connected to mounting plates. Telescopic components and the mounting frame are sequentially installed on the sides of the mounting plates, close to each other. Infrared sensors are symmetrically installed on the inner walls of both sides of the mounting frame, and the release paper passes through the mounting frame.

[0013] Preferably, the drive assembly includes a lead screw, a driven gear, a first guide rod, a second variable frequency motor, a driving gear, a sleeve, and a push plate. The lead screw consists of two parallel components, with both ends rotatably mounted on the inner walls of the support frame. The driven gear is mounted on the outer sides of both ends of the lead screw. The first guide rod is connected to the inner walls of both sides of the support frame. The second variable frequency motor is mounted on the inner walls of both sides of the support frame, positioned between the two parallel lead screws. The driving gear is mounted on the output ends of the second variable frequency motors on opposite sides, and meshes with the driven gears on both sides. Two sleeves are provided, each threaded onto the outer side of one end of the two lead screws, away from each other. The lower end of each sleeve also slidably mounts on the outer side of one guide rod on one side. The push plate is connected to the lower end of the sleeve and engages with the two sliding blocks at opposite ends.

[0014] Preferably, mounting bracket 1 is installed on the upper surfaces of both the front and rear sides of the support frame. The two ends of the lead screw are rotatably mounted on the front and rear mounting bracket 1, close to each other on one side. The two ends of the guide rod are connected to the front and rear mounting bracket 1, close to each other on one side. Mounting bracket 2 is also installed on the upper surfaces of both the front and rear sides of the support frame. The variable frequency motor 2 is mounted on the front and rear mounting bracket 2, close to each other on one side. The threads on the outer surfaces of the two parallel lead screws have opposite directions.

[0015] Preferably, the linkage component includes a slide groove, a slider, a second guide rod, a sleeve plate, and a top plate. The slide groove is formed on the upper end face of the bracket. The slider is slidably fitted in the slide groove, and the upper end of the slider extends through the slide groove to the top of the bracket and is connected to the lower end of the card seat through the extended end. The second guide rod is connected to the side of the bracket near the release paper roller. The sleeve plate is slidably fitted on the outside of the second guide rod. A rotating plate is rotatably connected between the sleeve plate and the card seat.

[0016] Preferably, a guide rod three is connected between the inner walls of the two sides of the slide groove, the slider is slidably sleeved on the outer side of the guide rod three, and a spring two sleeved on the outer side of the guide rod three is connected between the slider and the inner wall of the slide groove.

[0017] Preferably, the adjustment assembly includes a variable frequency motor, a connecting seat, a sleeve rod, and a bidirectional telescopic component. The output end of the variable frequency motor is connected to one end of the bonding roller, and both ends of the bonding roller are connected to the output end of the variable frequency motor.

The two output ends of the bidirectional telescopic component are respectively connected to the corresponding connecting seats on the upper and lower sides, which are close to each other on one side.

[0018] The beneficial effects of this invention are:

[0019] 1. The technical solution of the present invention is to clamp the release paper roller wound with release paper on the bracket, and to pass the release paper around each guide roller and through the space between the upper and lower bonding rollers. At the same time, the adhesive film wound on the unwinding roller also passes through the upper and lower bonding rollers. By adjusting the distance between the upper and lower bonding rollers, the release paper and adhesive film are pressed and bonded to one side by the upper and lower bonding rollers. At the same time, the support frame can be modularly set in multiple groups. Each support frame can be clamped with a roll of release paper through the bracket. In subsequent production, by increasing the number of support frames, multiple rolls of release paper and adhesive film can be laminated simultaneously, improving the flexibility of the device.

[0020] 2. The technical solution of the present invention connects the vacuuming device to the vacuuming frame and adjusts the angle of the mounting plate by a variable frequency motor, so that the vacuuming frame can be parallel to the release paper conveying direction and the cleaning brush installed in the vacuuming frame can contact the release paper bonding surface. This achieves cleaning of the bonding surface during the release paper conveying process, ensuring the quality of subsequent bonding with the adhesive film. In addition, when changing the release paper roller, the variable frequency motor can be controlled to run, driving the lead screws on both sides to rotate, thereby driving the two side frames and push plates to slide closer and then further away from each other. The push plates push the two side slides to slide closer and then further away from each other, thereby driving the upper and lower side levers of the vacuuming frame to slide back and forth, so as to move the cleaning brush to clean it. This avoids the accumulation of dust inside the cleaning brush due to long-term cleaning, which reduces the subsequent cleaning effect and further improves the bonding quality.

[0021] 3. The technical solution of the present invention uses the operation of the variable frequency motor 2 to drive the two side sleeve frames to slide closer to each other. The spring 2 will push the slider to slide and drive the rotating plate to rotate, thereby driving the sleeve plate to slide away from the bracket. At this time, the card seat will cancel the locking position of the rotating cylinder of the release paper roller at both ends, so as to facilitate the removal and replacement of the release paper roller, improve the roller changing efficiency, and also reduce the number of drive equipment to achieve flexible and efficient roller changing, reduce costs, and reduce drive components to facilitate subsequent operation and maintenance control.

[0035] The following will be combined with the appendix Figure 1 To be continued Figure 11 The technical solutions in the embodiments of the present invention have been clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0036] Example 1:

[0037] like Figures 1-11As shown, the present invention discloses a multi-layer composite release paper laminating device, including a support frame 1, a bracket 2 connected to the support frame 1, and two laminating rollers 4 on the support frame 1. A release paper roller 5 is rotatably sleeved on the bracket 2, and a rotating cylinder 6 is rotatably sleeved at both ends of the release paper roller 5. Release paper 7 is wound around the outside of the release paper roller 5 and passes between the upper and lower laminating rollers 4. A variable frequency motor 8 is installed on the inner walls of both sides of the support frame 1. The output ends of the variable frequency motors 8 on both sides are connected to mounting plates 9. Telescopic components 10 and mounting frames 11 are installed sequentially on the side of the mounting plates 9 on both sides. Infrared sensors 12 are symmetrically installed on the inner walls of both sides of the mounting frame 11, and the release paper 7 passes through the mounting frame 11. A dust collection frame 13 is connected to the mounting plate 9, and a cleaning brush 14 is installed on the side of the dust collection frame 13 near the release paper 7.

[0038] The dust collection frame 13 has sliding mounts 16 on both the upper and lower ends of the side away from the release paper 7, and the slide mounts 16 are connected to levers 17 that cooperate with the cleaning brush 14 to move. The support frame 1 is provided with a drive assembly, which is used to drive the upper and lower slide mounts 16 to move closer or further apart. The bracket 2 is slidably provided with a retainer 35 that fits against the outer side of the rotating drum 6. The bracket 2 is provided with a linkage assembly, which is used to move the linkage retainer 35 away from the bracket 2 when the two slide mounts 16 move away from each other, thus removing the retainer on the rotating drum 6. The support frame 1 is also provided with an adjustment assembly, which is used to adjust the distance between the upper and lower bonding rollers 4.

[0039] Several guide rollers 3 are rotatably mounted on the support frame 1. The guide rollers 3 are positioned between the release paper roller 5 and the upper and lower bonding rollers 4. On both sides of the support frame 1, there are also unwinding rollers 42 and rewinding rollers 43 respectively. A paper layer is sleeved on the outside of the unwinding roller 42, and the other end of the paper layer passes through the upper and lower bonding rollers 4 and is wrapped around the outside of the rewinding roller 43. The paper layer is located below each guide roller 3.

[0040] This device can be used in conjunction with existing unwinding roller 42 and rewinding roller 43. Multiple devices can be combined to meet the required number of release paper composite layers. Release paper 7 or adhesive film can be wound on the outside of the release paper roller 5 on each device, and release paper 7 or adhesive film can also be wound on the outside of the unwinding roller 42. By combining the number of devices and matching them with unwinding roller 42 and rewinding roller 43, the production of release paper with different composite layers can be achieved. When multiple devices are set up, they are connected in series so that each layer of release paper can be laminated to the next layer by the upper and lower laminating rollers 4 in the next device.

[0041] The dust collection frame 13 is connected to a high-powered dust collection fan via an air duct. The dust collection frame 13 is parallel to the conveying path of the release paper 7, and the cleaning brush 14 is attached to the bonding surface of the release paper.

[0042] By setting up the variable frequency motor 8, when the diameter of the release paper 7 or adhesive film wound on the release paper roller 5 gradually decreases as it is unwound, the angle between the release paper 7 or adhesive film and the first guide roller 3 will change. The dust collection frame 13 located between the first guide roller 3 and the release paper roller 5 can be angled by the variable frequency motor 8 to adapt to the angle change caused by the decrease in the diameter of the release paper 7 or adhesive film. The change in the angle of the release paper 7 can be monitored in real time by the infrared sensors 12 installed in the mounting frames 11 on both sides of the release paper 7, so as to ensure that the mounting plate 9 and the dust collection frame 13 are always parallel to the release paper 7 or adhesive film, and that the cleaning brush 14 in the dust collection frame 13 can clean the bonding surface of the release paper 7 or adhesive film.

[0043] The mounting frame 11 is located outside the dust collection frame 13, and the cleaning brush 14 is located outside both ends of the mounting frame 11. This allows the cleaning brush 14 to avoid the mounting frame 11 that is fitted on both sides of the release paper 7 or adhesive film, thus achieving thorough cleaning of the bonding surface of the release paper 7 or adhesive film without any blind spots.

[0044] The dust collection frame 13 has a sliding rod assembly 15 installed parallel to each other on the upper and lower ends of the side away from the release paper 7. The upper and lower sliding seats 16 are slidably sleeved on the upper and lower sliding rod assemblies 15 at opposite ends. Each sliding seat 16 and the end of the sliding rod assembly 15 are connected to a spring 18 sleeved on the outside of the sliding rod assembly 15.

[0045] The sliding sleeve of the slide block 16 and the slide rod assembly 15 can ensure the stability of the sliding. Under the action of the spring 18, the slide block 16 sleeved on the outer side of the upper and lower slide rod assemblies 15 will be in a state of mutual separation without the action of external force.

[0046] Example 2:

[0047] like Figures 1-11 As shown, the present invention discloses a multilayer composite release paper laminating device. Compared with Embodiment 1, this embodiment discloses the structure of the driving component.

[0048] The drive assembly includes a lead screw 20, a driven gear 21, a guide rod 22, a variable frequency motor 24, a drive gear 25, a sleeve 26, and a push plate 27. Two lead screws 20 are arranged parallel to each other, with both ends of the lead screw 20 rotatably mounted on the inner walls of the support frame 1. The driven gear 21 is mounted on the outer sides of both ends of the lead screw 20. Both ends of the guide rod 22 are connected to the inner walls of both sides of the support frame 1. The variable frequency motor 24 is mounted on the inner walls of both sides of the support frame 1, positioned between the two parallel lead screws 20. The drive gear 25 is mounted on the output ends of the two variable frequency motors 24, which are close to each other, and meshes with the driven gears 21 on both sides. Two sleeves 26 are arranged, each threaded onto the outer side of one end of the two lead screws 20, away from each other. The lower end of the sleeve 26 is also slidably mounted on the outer side of the guide rod 22 on one side. The push plate 27 is connected to the lower end of the sleeve 26 and engages with the two sliding blocks 16 at their respective ends, away from each other.

[0049] Mounting bracket 19 is installed on the upper surfaces of both the front and rear sides of the support frame 1. The two ends of the lead screw 20 are rotatably mounted on the front and rear mounting brackets 19, close to each other on one side. The two ends of the guide rod 22 are connected to the front and rear mounting brackets 19, close to each other on one side. Mounting bracket 23 is also installed on the upper surfaces of both the front and rear sides of the support frame 1. The variable frequency motor 24 is installed on the front and rear mounting bracket 23, close to each other on one side. The threads on the outer surfaces of the two parallel lead screws 20 are turned in opposite directions.

[0050] By controlling the operation of the variable frequency motor 24, the meshing of the active gear 25 with the driven gears 21 on both sides can drive the lead screws 20 on both sides to rotate, thereby causing the sleeves 26 on both sides to slide closer or further away from each other on the outer side of their respective lead screws 20. When they slide closer to each other, the sleeves 26 will first slide closer to each other, and after passing the intersection point, which is the middle of the lead screws 20, they will slide further away from each other. The push plates 27 connected to the lower ends of the sleeves 26 on both sides have different shapes to avoid obstructing each other at the intersection point.

[0051] Furthermore, when the two sleeve frames 26 move closer to each other during the winding process, they can abut against the two sliding blocks 16 and slide closer to each other, compressing the springs 18 on each side. This causes the lever 17 to reciprocate the cleaning brush 14, shaking off the accumulated dust and preventing poor cleaning performance caused by the cleaning brush 14 itself becoming dirty during long-term use.

[0052] Example 3:

[0053] like Figures 1-11 As shown, the present invention discloses a multi-layer composite release paper laminating device. Compared with Embodiment 2, this embodiment discloses the structure of the linkage component.

[0054] The linkage assembly includes a slide groove 33, a slider 34, a second guide rod 36, a sleeve plate 37, and a top plate 39. The slide groove 33 is opened on the upper end face of the bracket 2. The slider 34 is slidably sleeved in the slide groove 33, and the upper end of the slider 34 extends through the slide groove 33 to the top of the bracket 2 and is connected to the lower end of the card seat 35 through the extended end. The second guide rod 36 is connected to the side of the bracket 2 near the release paper roller 5. The sleeve plate 37 is slidably sleeved on the outside of the second guide rod 36. A rotating plate 38 is rotatably connected between the sleeve plate 37 and the card seat 35. The top plate 39 is connected to the side of the sleeve plate 37 near the release paper roller 5 and cooperates with the push plate 27 to abut.

[0055] A guide rod 30 is connected between the inner walls of the two sides of the slide groove 33. The slider 34 is slidably sleeved on the outer side of the guide rod 30. A spring 2 41 sleeved on the outer side of the guide rod 30 is connected between the slider 34 and the inner wall of the slide groove 33.

[0056] When the two sleeve frames 26 move closer to each other, the sleeve frames 26 will move away from the top plate 39 on their respective sides. Then, under the action of the second spring 41, the card holder 35 will push the slider 34 and the card holder 35 to slide. The card holder 35 will also push the rotating plate 38 to rotate, thereby causing the sleeve plate 37 and the top plate 39 to slide continuously and come into contact with the push plate 27. Until the sleeve plate 37 and the guide rod 36 come into contact with the end of the bracket 2 and are limited, the top plate 39 will separate from the push plate 27. During this process, the sliding of the card holder 35 will cancel the locking of the rotating cylinder 6 that is rotated and sleeved at both ends of the release paper roller 5, so as to facilitate the efficient and flexible rewinding of the release paper 7 or adhesive film wrapped on the outside of the release paper roller 5 after unwinding.

[0057] Since the sliding of the sleeve frame 26 will change the positioning of the rotating drum 6 on both sides of the release paper roller 5, when the sleeve frame 26 drives the push plate 27 to push the slide block 16 and drive the lever 17 to clean the cleaning brush 14, it should be done simultaneously when changing the release paper roller 5. This can ensure the stability of the release paper roller 5 during operation, and also ensure that the cleaning brush 14 remains stable during the delivery of the release paper 7 or adhesive film, thus preventing the release paper 7 or adhesive film from breaking.

[0058] Example 4:

[0059] like Figures 1-11 As shown, the present invention discloses a multi-layer composite release paper laminating device. Compared with Embodiment 3, this embodiment discloses the structure of the adjustment component.

[0060] The adjustment assembly includes a variable frequency motor 28, a connecting seat 29, a sleeve rod 31, and a bidirectional telescopic component 32. The output end of the variable frequency motor 28 is connected to one end of the bonding roller 4, and both ends of the bonding roller 4 are connected to the output end of the variable frequency motor 28. The connecting seat 29 is connected to the end of the variable frequency motor 28 away from the bonding roller 4. Both ends of the connecting seat 29 are connected to sleeves 30. The sleeve rod 31 is connected to the front and rear inner walls of the support frame 1. The sleeves 30 are slidably sleeved on the outside of the sleeve rod 31. The output ends on both sides of the bidirectional telescopic component 32 are respectively connected to the corresponding connecting seats 29 on the upper and lower sides, which are close to each other on one side.

[0061] This allows the adjustable spacing of the upper and lower bonding rollers 4 to move closer or further apart by controlling the bidirectional telescopic component 32, so as to facilitate the pressing and bonding of the release paper 7 and the adhesive film passing between them.

[0062] Based on the disclosure and teachings of the foregoing specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, the present invention is not limited to the specific embodiments disclosed and described above, and some modifications and changes to the present invention should also fall within the protection scope of the claims of the present invention. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on the present invention.
